Humans have 23 pairs of chromosomes, including a pair of sex chromosomes (typically XX for females, and XY for males). Chromosomes contain hundreds to thousands of genes, which are sections of DNA ...

Robertsonian chromosomes (ROB) are a type of structurally variant chromosome that is created when two chromosomes fuse together to form an unusual bond. Found commonly in nature, these chromosomes are ...

DNA methylation is a key epigenome component that helps dictate how genes are expressed, contributing to normal cell and tissue differentiation during development, as well as the process of biological ...

DNA can voyage along intercellular highways called tunneling nanotubes. It’s a phenomenon that could potentially spread tumor ...
